AGATA Simulation working group activities overview Marc Labiche (marc. labiche@stfc. ac. uk) 17 th AGATA week, IPN Orsay - 5 th Oct 2016
Outline Ø AGATA SWG – recent activities § GANIL-SPIRAL 2 ICC Workshops on simulation Ø AGATA Code – recent/future developments § GPS & GDML capability § Additional Ancillaries Ø Update on Simulated Photopeak efficiency curves § Simulated efficiency & P/T curves for GANIL Configurations § Validation of simulation / GSI source run
Recent Activities (1/2) ICC Simulation workshop (Nov 2015): Ø Presentations and Tutorials on: Ø AGATA code (M. Labiche) Ø Including a demo with LYCCA and a demo on Simulated Time Stamped data Ø STo. Gs toolkit (O. Stezowsky, I. Companis) Ø Detectors available: PARIS, AGATA, EXOGAM, FATIMA, N-Wall, DIAMANT, … Ø All Geometry are defined in gdml format Ø Could become the new framework for AGATA in if more and more users start using it and develop it. (Connectivity to Gamma. Ware & Femul) All slides are still available here: https: //npg. dl. ac. uk/ICC-simulation/ICCWorkshop. Sim 2015
Recent Activities (2/2) New ICC Simulation workshop 29 th Nov -1 st Dec 2016 Ø Presentations and Tutorials on NPTool framework § User friendly framework (GEANT 4 + ROOT) § MUST 2, GASPARD, MUGAST, TIARA, HELIOS, PARIS, FATIMA …. § Built-in event generators for the kinematics of direct reactions. § Also GDML compatible Ø AGATA geometry could easily be exported into NPTool New Git. Hub repository for gdml files: https: //github. com/malabi/gdml-files
Recent developments GEANT 4 General Particle Source § GPS allows the user to simulate realistic sources (ex: 60 Co, 152 Eu, § Now also available in the AGATA code: . /Agata –gps § Ex. Macros also available in the GANIL branch svn repostory: agata/branch/GANIL/trunk/macros/gps 152 Eu However: Issues with some intensities ! …)
Recent developments GEANT 4 GDML capability added § Implement Mechanical structure § Easy to include as ancillary: . /Agata –a N id § Honey. Comb is invoked as ancillary with id number: 26 § Ganil vacuum chamber + target frame has the id number: 27 § OUPS (unique id not yet attributed) § Import/export detector from/to other framework
Future developments Ø Other ancillaries (? ) Ø NEDA Ø Not yet part of the AGATA svn repository. Ø Based on AGATA Code, but not defined as ancillary yet ! Ø DIAMANT (? ) Ø No update received. Ø Existing geometry file in ASC to be updated ? Ø New chamber to be added Diamant as currently defined in ASC

Sim (%) Core Common 2. 38(2) 2. 84(9) Calorimeter 3. 30(2) 4. 21(8) So: ~20% discrepancy on the Core Common Efficiency ~33% discrepancy on the Calorimeter Efficiency

Summary Implementation of GEANT 4 GPS & GDML capability New “Ancillaries” added to the ASC svn repository using GDML But NEDA & DIAMANT new chamber still needs to be added Vacuum Chamber has a significant attenuation impact on Efficiency & P/T ratio at low energy. Any Ancillary detector inside the chamber would also have an impact E 2 Ang. Corr. and bbeam (10%) have also an effect on Efficiency but almost none on P/T, as it seems. Simulation of the GSI source measurement have been corrected but still overestimate the experimental efficiency. GANIL source measurement would also be interesting to compare with.
